Amazon's Alexa will be built into all new homes from Lennar

The homes all come with WiFi, smart thermometers, lighting, doorbells and locks pre-installed, and Amazon's voice-activated Alexa personal assistant devices to run them. The experience centers offer customers the chance to interact with the technology in a real-life setting. Lennar announced Wednesday that standard features in its new homes will include built-in Wi-Fi, smart locks, doorbells, thermostats and lights -- all controlled by Alexa, Amazon's voice-activated digital assistant. Each house will come with two Alexa-enabled smart speakers, an Echo Show and an Echo Dot. New homeowners will also get a free visit from an Amazon technician to help set everything up and teach them how to use it.
